Tetralogy of Fallot associated with chromosome 22q11 deletion

In summary, all patients with tetralogy and 22qH deletion had 1 to 4 additional conotruncal anomalies, such as high aortic arch, right aortic arch, infundibular septal defect, aberrant origin of the subclavian artery, major aortopulmonary collateral arteries, and anomalous ductus arteriosus causing isolation of either the left pulmonary artery or the subclavian artery.
